Description
GK Series Hydraulic Rod Ends
GK..DO series hydraulic rod ends with cylindrical section welding shank, steel/steel construction, requiring maintenance. Rod end with welding shank consists of a rod end housing and a radial spherical plain bearing (GE...E or GE...ES). The rod end housing is manufactured from weldable steel, featuring a dowel pin in the shank bottom and welding chamfer. This design allows for convenient relubrication via a nipple or hole.
Key Features
  • For shaft diameters from 10 mm to 80 mm
  • Concentric locating pin on shank base and 45º welding chamfer
  • Spherical plain bearing located in housing by staking on both sides
  • Designed for piston rod ends and cylinder bases
  • Available with maintenance-free spherical plain bearings
Material Specifications
General Purpose Material:
  • Housing: construction steel S 355 J2G3 (St 52-3 N) (1.0570)
  • Bearing: GCr15(52100,100Cr6) bearing steel, phosphate treated
Corrosion Resistant Material:
  • Housing: AIS316 stainless steel
  • Bearing: AISI420 stainless steel
  • Liner: PTFE fabric
  • Shaft diameter: 20~50mm

Usage Instructions
1. Safety & Preparation
  • Wear appropriate PPE (safety glasses, gloves, welding helmet)
  • Clean all parts thoroughly before installation
  • Ensure bearing moves freely without obstruction
  • Identify the dowel pin on shank bottom
  • Drill matching hole in mounting plate for pin alignment
2. Welding Procedure
  • Use standard arc welding (MIG/TIG recommended)
Critical: Prevent bearing heat damage during welding
  • Use a heat sink near the bearing area
  • Weld in short, staggered segments and allow cooling between passes
  • Avoid continuous welding around the circumference
  • Fill the welding chamfer completely for optimal strength
3. Post-Weld Procedures
  • Allow to cool naturally - do not quench
  • Inspect weld quality and integrity
  • Verify bearing still moves freely without binding
  • Relubricate immediately (for types with nipple/hole)
  • Install linkage bolt through bearing inner ring and secure properly
Buyer's Guide
Choose the Correct Series
  • GE...E / GE...ES: General industrial linkages
    • E: Steel-on-steel, requires relubrication. Higher load capacity
    • ES: Coated surface, often maintenance-free operation
  • GK Series: Use specifically for hydraulic cylinder connections
    • Heavy-duty construction for high shock loads
    • Enhanced seals for harsh industrial environments
Key Specifications to Verify
  • Size compatibility (bolt bore, housing diameter)
  • Static Load Rating (C0) - Most critical parameter for welded ends
  • Angular misalignment capability
  • Shank dimensions and chamfer specifications
Material & Environmental Considerations
  • Housing/shank material: Weldable steel construction
  • Seal type (standard rubber or specialty materials)
  • Lubrication temperature operating range
Selection Checklist
✓ Request technical datasheets with complete load ratings
✓ For hydraulic applications, specify GK series
✓ Confirm warranty coverage and installation requirements
✓ Verify material compatibility with operating environment
✓ Ensure proper sizing for intended application
